The La Sagrada Familia is the only cathedral in the world which is still under construction. It is only funded by churchgoers and devotees, and through ticket revenue from visitors. It is Gaudí's dream, to which he devoted much of his life. At the time of his death in 1926, only one of the towers had been completed. The continuation of Gaudí's project has become an unmistakable symbol of the Barcelona, not just because of its spectacular size, but because it also reveals the spirit of a city which always been committed to building its future.
